Hi I just got a mbp 2.26Ghz 13inch with screen model 9C9E I've read some got screen model 9C9F and more. But I find my screen is not very impressive at all infact, I think it's not much different form the UMB. is there any difference between the 2.26 & 2.53's screen? and some with the same 2.26Ghz model yet having different model of screen of different screen quality. Yet mine have a bad color saturation as well as a very low brightness.
